23 Environmental Management Framework

23.1 Introduction This section presents the Environmental Management Framework (EMF) that has been developed for Melbourne Metro. The EMF provides a transparent and integrated governance framework to manage environmental aspects as described in this EES for the design, construction and operational phases of the project. The EMF includes the recommended Environmental Performance Requirements that define the project-wide environmental outcomes that must be achieved during design, construction and operation of Melbourne Metro (regardless of the design solutions adopted). Once approved, compliance with the EMF and the Environmental Performance Requirements will be enforced by MMRA through the contractual arrangements for delivery of the project.

The recommended Environmental Performance Requirements have been developed through the EES to address the identified environmental risks and impacts. The performance-based approach that forms the Environmental Performance Requirements aims to achieve outcomes that provide a net community benefit, while allowing for a delivery model with sufficient flexibility to encourage innovation by the private sector to determine how any recommended Environmental Performance Requirements would be achieved. The EMF outlines clear accountabilities for the delivery and monitoring of the achievement of the Environmental Performance Requirements so that the environmental effects and hazards of the project would be managed.

Design and management measures incorporated into the Concept Design, together with implementation of and compliance with the EMF and the Environmental Performance Requirements would ensure compliance with statutory requirements during design, construction and operation. The contractual arrangements for delivery of the EMF and Environmental Performance Requirements would be in the form of Project Contracts between MMRA and the contractors delivering the different parts of Melbourne Metro.

The EMF requires that the contractors develop and implement an Environmental Management System (EMS) certified to AS/NZS ISO 14001:2015 Environmental management systems — Requirements with guidance for use and consistent with relevant legislation, policy and guidelines and MMRA’s Environmental Policy. The purpose of the EMS is to ensure that works are planned and performed so that the adverse effects on the environment are either avoided or minimised and are carried out in accordance with the approved Environmental Performance Requirements.


The EMS will provide a structured approach for monitoring the implementation of Construction Environmental Management Plans (CEMPs) for project delivery and the Operations Environmental Management Plan (OEMP) for the tunnels and stations. The EMS, CEMPs and OEMP can then be audited throughout the project as a mechanism for continuous improvement. Refer to Sections 23.7 and 23.8 for a description of the management plans and requirements for ongoing monitoring of their implementation.

The development of the EMF is guided by the EES Scoping Requirements, relevant legislation, policy and guidelines, and has been informed by the environmental risk assessment and specialist environmental impact assessment studies completed for the EES. The risk assessment has been undertaken in accordance with the risk management standard AS/NZS/ISO31000:2009 and would be maintained throughout the project in accordance with the MMRA EMS.

23.1.1 Works Covered by the EMF The infrastructure proposed for construction of Melbourne Metro and assessed in this EES includes:

•

•

•

•

Twin nine-kilometre rail tunnels from Kensington to South Yarra, travelling beneath Swanston Street in the Melbourne CBD and connecting the Sunbury and Cranbourne/Pakenham railway lines

Five new underground stations at Arden, Parkville, CBD North, CBD South and Domain, with CBD North and CBD South stations featuring direct interchanges with the existing Melbourne Central station and Flinders Street Station respectively

A new transport interchange at Domain

Rail tunnel portals (entrances) at Kensington and South Yarra.

The project would also require track work (a turnback) at West Footscray to enable trains using the Sunbury Line to turn around before reaching Sunbury and head back through the Melbourne Metro tunnels.

The project includes the operation of the five new stations and tunnels; however, it does not include the operation of the whole rail network. Figure 23-1 shows a broad schematic plan for the principal inner Melbourne components of Melbourne Metro.

23.2 Scoping Requirements and EMF Structure

The EES Scoping Requirements relevant to the EMF include the following draft evaluation objective:

• Environmental Management Framework – To provide a transparent framework with clear accountabilities for managing environmental effects and hazards associated with construction and operation phases of the project, in order to achieve acceptable environmental outcomes.

The EMF outlined in this chapter addresses this objective in the following sections:

•

•

•

•

Governance framework and roles and responsibilities to provide a transparent framework for accountability (Section 23.3 and 23.4)

Environmental risk and impact assessment for identifying potential environmental effects and hazards to be managed (Section 23.5)

Recommended Environmental Performance Requirements to achieve acceptable environmental outcomes (Section 23.6)

Document hierarchy to outline how the EMF would be implemented (Section 23.7)


•

•

•

Environmental Management System for achieving compliance with CEMPs (Section 23.7.1)

Evaluation and compliance requirements, including monitoring, reporting and auditing (Section 23.8)

Contingency measures to address identified environmental, social and business risks during construction and operational phases (Section 23.9).

23.3 Governance Framework As discussed in Chapter 1, the Victorian Government has announced the procurement strategy for Melbourne Metro, which is structured around four works packages:

•

•

•

•

A Managing Contractor for early works together with procurement by Utility Service Providers and Yarra Trams

An Availability Public Private Partnership (PPP) for the tunnels and stations

Competitive alliance for rail infrastructure associated with the eastern and western portals and the western turnback

Competitive alliance for rail systems for high capacity signalling, rail systems integration and commissioning (outside the scope of the EES).

For each works package, a contractor would be appointed under the contractual framework applicable to the respective procurement model (Project Contract). MMRA would administer each Project Contract on behalf of the State Government.

Project Contracts would detail the applicable contractor’s obligations for delivery of the relevant works. Project Contracts would require each contractor to:

•

•

•

•

Comply with the EMF

Comply with the Environmental Performance Requirements

Comply with the MMRA EMS

Develop, implement and maintain a project specific EMS, CEMP for the project and site Specific Environmental Implementation Plans (SEIPs) for the design and construction phases, where applicable.

The PPP contractor would also have to develop, implement and maintain an OEMP for the elements of the infrastructure for which they would be responsible.

The governance framework for Melbourne Metro is presented in Figure 23-2.

A description of each procurement package is provided in Table 1-3 of Chapter 1 Introduction of this EES. The Rail Systems and Rail Infrastructure Alliances are proposed to include wider network works that have not been assessed in this EES and for which assessment and approvals would be undertaken separately.

The procurement process for each works package would include the requirement for bidders to develop outline EMPs (as part of the bid submission) for construction and operation (for tunnels and stations). These outline EMPs would enable the contractors to demonstrate their approach to achieving compliance with the EMF. MMRA would review and assess the outline EMPs against the requirements of the EMF.

Following contract award and prior to construction commencing, the successful contractors would be required to develop and implement a project specific EMS and CEMP to meet the requirements of this EMF and the MMRA EMS. The successful PPP contractor would maintain elements of the infrastructure delivered for Melbourne Metro and would also have to develop and implement an OEMP to meet the requirements of the EMF.


The EMS, CEMP and OEMP would describe in detail how the contractor would meet the approved Environmental Performance Requirements and approval conditions and identify, manage and mitigate environmental risks arising during design, construction and operation. Specific requirements for the contractor's documentation are outlined in Section 23.7.

MMRA would audit the early works contractors and Rail Infrastructure Alliance to assess compliance with the Environmental Performance Requirements and conformance with the EMS and CEMPs.

The auditing of the PPP contractor would be done independently, as is required for a PPP contract, and is described below:

•

•

•

The PPP contract would have an Independent Reviewer and Independent Environmental Auditor

An Independent Reviewer would be appointed jointly by MMRA and the PPP contractor to review the CEMP, OEMP, contractor documentation and environmental audit reports, and to monitor the contractor's compliance with the EMF

An Independent Environmental Auditor would also be appointed by the PPP contractor to undertake environmental audits of compliance with the approved CEMP, OEMP and approval conditions. The Independent Environmental Auditor would be required to prepare audit reports and provide these to MMRA, the Independent Reviewer, the Minister for Planning and other Regulators and agencies (as appropriate).

23.4 Roles and Responsibilities MMRA, on behalf of the State Government, is the proponent for this project and is responsible for delivering Melbourne Metro by 2026, in line with the requirements and objectives of PTV and the Victorian Government.

MMRA is an Administrative Office established under the Office of the Coordinator General and is one of several agencies assisting the State Government to achieve its integrated transport policy objectives. The MMRA Chief Executive Officer is accountable to the Minister for Public Transport, reporting to the Secretary of the Department of Economic Development, Jobs, Transport and Resources.

MMRA is responsible for overseeing and engaging contractors and consultants for all aspects of the project including planning and development of a project Concept Design, site investigations, stakeholder engagement, obtaining planning approvals and procurement, through to construction delivery and project commissioning.

Fulfilling the responsibilities and accountabilities across all elements of the EMF involves MMRA, contractors and regulators. The contractors' responsibilities would be included as contractual conditions in Project Contracts. The contractors would also be responsible for activities conducted by their sub-contractors.


At the completion of construction and project commissioning, PTV would become responsible for the ongoing operation and maintenance of the train services and infrastructure delivered by Melbourne Metro, other than any infrastructure which is to be operated and maintained by the PPP contractor for the term of the PPP contract.

The key roles and responsibilities are shown in Table 23–1.

23.5 Risk and Impact Assessment Environmental risks and impacts have been identified and assessed through the specialist investigations for the EES and a detailed environmental risk assessment process. As described in Chapter 4 of the EES, the objective of the environmental risk assessment is to identify key social, environmental and business risks associated with construction and operation of the project, and to develop management and mitigation measures to reduce these risks. Technical Appendix B Environmental Risk Assessment Report contains further detail on the risk assessment and the complete risk register developed for the EES.

The environmental risk assessment developed for the EES forms a key component of the EMF. This risk assessment would be 'live' and updated periodically to reflect the project status and any new information arising.

As part of their EMS, the contractors would be required to develop a detailed environmental risk assessment based on the detailed design of the project and consider the risks identified in the EES. The risk assessment would be required to be consistent with AS/NZS ISO 31000:2009 Risk management – principles and guidelines. The contractors would be required to maintain a current risk register which would be ‘live’, adopting regular reviews and updating the register in response to changes to design, construction or operational activities, work methods, new technology, legislation and policy, or the occurrence of incidents or complaints.

23.6 Environmental Performance Requirements

Melbourne Metro will be delivered in accordance with approved Environmental Performance Requirements. Environmental Performance Requirements define the project-wide environmental outcomes that must be achieved during design, construction and operation of Melbourne Metro (regardless of the design solutions adopted).

This performance-based approach of the Environmental Performance Requirements aims to achieve outcomes that provide a net community benefit, while allowing for a delivery model with sufficient flexibility to encourage innovation by the private sector to determine how any recommended Environmental Performance Requirements would be achieved.

Many Environmental Performance Requirements require consultation to be undertaken with relevant stakeholders. The extent of consultation and outcomes would be documented to demonstrate compliance with the Environmental Performance Requirements. In instances where an Environmental Performance Requirement necessitates the involvement of a ‘responsible authority’, this is defined as the relevant responsible authority for the requirement specified. The responsible authority may be the Minister for Planning, local council, Melbourne Water, VicRoads, etc.


Proposed mitigation measures identified in this EES to avoid, reduce or offset environmental impacts form the basis of the recommended Environmental Performance Requirements for Melbourne Metro. These measures have been recommended by specialists through the EES assessment process.

The approach adopted to assess environmental risks and impacts and develop the Environmental Performance Requirements is described in Chapter 4 EES Assessment Framework and Approach. Specific requirements are discussed in the relevant sections of Chapters 8 to 22 of this EES.

The recommended Environmental Performance Requirements are presented in Table 23–2. They cover the following subject areas:

•

•

•

•

•

•

•

•

•

Aboriginal cultural heritage

Air quality

Aquatic ecology and river health

Arboriculture

Business

Contaminated land and spoil management

Greenhouse gas emissions

Groundwater

Ground movement

•

•

•

•

•

•

•

•

•

Historical cultural heritage

Land use and planning

Landscape and visual

Noise and vibration

Surface water

Social and community

Terrestrial flora and fauna

Transport

Urban design.

The EMF, including all recommended Environmental Performance Requirements, would be implemented through Project Contracts for the delivery of Melbourne Metro. Under the proposed planning scheme controls for Melbourne Metro, the EMF and Environmental Performance Requirements would also need to be approved by the Minister for Planning.

The EMF and the Environmental Performance Requirements will be updated by MMRA prior to awarding the contracts to ensure all approval conditions of the planning controls applied under the Planning Scheme Amendment as specified by the Minister for Planning are captured.

NV2 For construction works conducted between CBD South station and Domain station, comply with the requirements of the Notification of Referral Decision for the Melbourne Metro Rail Project (EPBC 2015/7549, dated 22 September 2015) under the EPBC Act for vibration monitoring and measurement, as follows: • Conduct pre-construction dilapidation surveys of the nearest Commonwealth Heritage listed

structures to the construction activity, including the Former Guardhouse (Block B), to record structural condition and structural integrity prior to commencement of tunnelling

• Conduct vibration monitoring at the commencement of tunnelling in geological conditions that are similar to those at Victoria Barracks in order to quantify the actual tunnel boring machine vibration characteristics (level and frequency) for comparison to the values derived from the literature and the German DIN (DIN 4150) target

• Conduct continuous vibration monitoring at the nearest Victoria Barracks heritage structures to the construction activity, including the Former Guardhouse (B Block), to assess the actual tunnelling vibration for acceptability, taking into account both the vibration frequency and condition of structures, until monitoring of vibration at the Former Guardhouse (B Block) shows measurements equivalent to preconstruction vibration readings at the Former Guardhouse (B Block)

• If monitoring conducted according to the above demonstrates the condition of heritage structures may be degraded as a result of vibration, ground vibration must be reduced by adjusting the advance rate of the tunnel boring machine until monitoring of vibration at the Former Guardhouse (B Block) shows consistent measurements equivalent to preconstruction vibration readings at the Former Guardhouse (B Block).

3 3 to 8 8 to 10 8

Notes 1 At frequencies above 100 Hz, the values given in this column may be used as minimum

values. 2 Vibration levels marginally exceeding those vibration levels in the table would not

necessarily mean that damage would occur and further investigation would be required to determine if higher vibration levels can be accommodated without risk of damage.

3 For civil engineering structures (e.g. with reinforced concrete constructions used as abutments or foundation pads) the values for Type 1 buildings may be increased by a factor of 2.

4 Short-term vibration is defined as vibration which does not occur often enough to cause structural fatigue and which does not produce resonance in the structure being evaluated.

Groundwater


GW1 Design the tunnel and underground structures so that they minimise groundwater drawdown during construction and operation to minimise impacts on groundwater dependent values, ground movement and contamination plume migration.

All Design GW001 to GW059

GW2 Develop a groundwater model for the detailed design phase to predict impacts associated with any changes to construction techniques or operational design features proposed during detailed design, and reconfirm that the Environmental Performance Requirements and mitigation measures are sufficient to mitigate impacts from changes in groundwater levels, flow and quality. Undertake monitoring during construction to ensure that predictions are accurate and mitigation measures are appropriate.

All Design GW001 to GW059

GW3 Develop and implement a Groundwater Management Plan (GMP) detailing groundwater management approaches to address the predicted impacts to groundwater dependent values during construction. The GMP must be based on the detailed design phase groundwater model, and should include the following details:

• Approach to collection, treatment and disposal of groundwater collected during construction in accordance with the MMRA Groundwater Disposal Strategy

• Identifying and if necessary, specifying mitigation measures to protect groundwater dependent vegetation during periods of drawdown

• An approach identified in consultation with the EPA so that contaminant migration cause no significant impacts on beneficial uses and vapour intrusion into underground structures, and establish appropriate monitoring networks to confirm effectiveness of approach

• Methods for minimising drawdown in areas of known PASS and establishing appropriate monitoring networks to confirm effectiveness of approach

All Construction GW001 to GW059




• Methods for minimising drawdown at any existing recharge bores, and establishing appropriate monitoring networks to confirm effectiveness of mitigation

• Groundwater drawdown trigger levels for groundwater dependant values at which additional mitigation measures must be adopted

• Design, operation and management of groundwater injection borefields

• Contingency measures if impacts occur at existing active groundwater bores and surface water bodies

• Contingency measures should unexpected groundwater conditions be encountered. The GMP must satisfy the EPA and relevant water authorities that groundwater dependent values would be protected. The GMP should also address MMRA’s sustainability requirements where appropriate.

GW4 Use the Groundwater Disposal Strategy and GMP to obtain a Trade Waste Agreement with the relevant Water Retailers for groundwater disposal.


GW055, GW056

GW5 Develop and implement a groundwater monitoring plan as part of the GMP that details sufficient monitoring of drawdown to verify that no significant impacts occur from potential: • Contaminant migration on the beneficial uses of groundwater at third party properties

caused by drawdown and vapour intrusion to underground structures • Activation of PASS and groundwater acidification

• Reduction in access to water for bore owners in the area around the project

• Reduction in access to groundwater for trees– particularly in the Tunnels precinct between CBD South and Domain stations, and the CBD South station and eastern portal precincts

• Change in groundwater levels in any existing recharge bores that may be present in the area around the project.

23.7 Environmental Management Documentation

23.7.1 Overview The EMF is made up of a number of key pieces of documentation from MMRA (on behalf of the State Government) and the contractor, as well as relevant legislation and approvals that must be complied with (refer to Figure 23-3). At the State level, MMRA would be the owner and administrator of the Environmental Performance Requirements, MMRA Environmental Policy, MMRA EMS and statutory decisions and approvals.

The Environmental Vision stated in the MMRA Environmental Policy is:

"to be an industry leader in managing the environmental impacts of delivering major infrastructure projects".

The MMRA EMS (aligned to AS/NZS ISO 14001: 2015 Environmental management systems – requirements with guidance for use) would outline and track compliance with the environmental management responsibilities for all parties including the delivery contractors (the contractors). Additional MMRA strategies and plans include the Cultural Heritage Management Plan (currently under development), the Urban Design Strategy and the Community and Stakeholder Engagement Plan.

MMRA would also be responsible for administering the Project Contracts on behalf of the State Government in accordance with its EMS and procedures.

The contractors would each be required to develop and implement a project-specific EMS for construction of the project that is certified to AS/NZS ISO 14001: 2015 and consistent with the MMRA EMS. The purpose of the EMS would be to establish a system whereby environmental risks and impacts are managed and there is a process for identifying opportunities of continual improvement across the project.

MMRA together with the contractors would prepare plans to comply with the approval conditions of the planning controls applied under the Planning Scheme Amendment. Each contractor would also be required to prepare a Construction Environmental Management Plan (CEMP), Site Environment Implementation Plan(s) (SEIPs) and a Traffic Management Plan for the construction phase. For the operations phase, the PPP contractor would be required to prepare an Operations Environmental Management Plan (OEMP).

A detailed description of the key documentation elements of the EMF is provided in Table 23–3.

• Set out design criteria that, along with further detailed content, will inform the technical specifications for project’s procurement phase.



State (MMRA) and contractor

Plans to comply with the Incorporate Document

MMRA and the contractors would prepare the detailed plans required to comply with planning scheme amendment conditions including a CEMP, SEIP and TMP as relevant to any stage of the project. Development plans would be prepared for surface works as required by conditions of the Incorporated Document. The plans would be prepared in consultation with agencies relevant to each plan including Councils, Heritage Victoria, EPA, Melbourne Water, Public Transport Victoria, Office of Victorian Government Architect (OVGA) and VicRoads. Plans would be developed once the detailed design and refined construction methodology is prepared by each contractor. Relevant agencies would be consulted on the details and complying with their requirements.

Contractors

EMS The contractor’s EMS would be required to be certified to AS/NZS ISO 14001: 2015 Environmental management systems – requirements with guidance for use. The EMS would be aligned to the requirements of the MMRA EMS.

Construction Environmental Management Plan (CEMP)

The CEMP would reflect the requirements of the EMF and EPA Publication No. 480, Environmental Guidelines for Major Construction Sites. The CEMP would be developed to take into account:

• Each construction site’s environmental features

• The nature of the works to be undertaken

• Potential environmental impacts as identified in the EES and activity specific environmental risks

• Permits and/or approvals and related conditions

• The findings of environmental investigations undertaken by or on behalf of MMRA

• The findings of any environmental investigations undertaken by the contractor.

The contractor may choose to develop one CEMP for the entire project or individual CEMPs for each precinct or component of the works. Similarly, the contractor may choose to address all of the above environmental impacts within one CEMP or a series of sub-plans for each environmental value. The exception to this is where an Environmental Performance Requirement requires the development of a specific management plan.



Operations Environmental Management Plan (OEMP) (for PPP contract)

The PPP contractor or franchisee as relevant would develop an OEMP to reflect the requirements of the EMF and would consider: • The nature of operational activities and environmental features of

each station and components of the tunnels being operated

• Identification of the environmental issues to be managed and the measures to be taken to meet the Environmental Performance Requirements

• Compliance with approval conditions and legislation

• Interface with existing stations at Flinders Street and Melbourne Central

• Emergency and incident management The contractor may choose to have separate or a consolidated OEMP for the different elements of the infrastructure, depending on the impacts to be managed.

Traffic Management Plan (TMP)

The TMP would provide the means by which the contractor would minimise disruption to traffic, car parking, pedestrian and bicycle movements during construction.

Site Environment Implementation Plans (SEIPs)

Site specific plans identifying site-specific environmental control measures to be implemented.

Work Method Statements

Description of work activities, approvals required and risk assessment and control measures.

Records and Checklists

• Monitoring and inspection records

• Checklists (e.g. environmental site inspection checklist)

• Records (e.g. training/competency records, waste transport and disposal certificates).

23.7.2 Change Management Revisions to MMRA and contractor documentation may be required as a result of changes in activities and work practices, changes to legislation, risks, or as a result of findings from internal or external audits, incidents or complaints. The contractors' EMS, CEMP and OEMP would be controlled documents and would be developed, approved, implemented and revised in accordance with Table 23–4.

The contractor would be required to submit all major revisions to environmental documentation to MMRA for approval. Major revisions are defined as changes that affect work practices, roles and responsibilities, environmental risks and overall project delivery. Minor revisions are defined as addressing typographical errors, formatting and other administrative detail.

An outline of the review and approval requirements for the key environmental management documents of the EMF is provided in Table 23–4.

23.8 Evaluating Environmental Performance Outcomes

The contract specifications would include compliance requirements for the contractor including monitoring, reporting to the MMRA and relevant government agencies, and internal and external environmental auditing. A summary of these compliance requirements is provided in this section.

The MMRA EMS would describe the project's environmental compliance system, including:

•

•

•

•

Definitions of what constitutes a non-conformance

Requirement for a non-conformance tracking register

Timeframes and responsibilities for addressing non-conformances

Detailed procedures for monitoring, auditing and reporting.

23.8.1 Monitoring A range of monitoring programs would be specified in each contractor's CEMP and the PPP contractor’s OEMP to enable conformance to and measurement of delivery of Environmental Performance Requirements. The parameters to be monitored and the frequency of monitoring would reflect regulatory requirements and the level of potential risk to the environment. Monitoring would include periodic inspections of construction works areas and assets constructed.

The CEMP would be required to be reviewed regularly to verify that:

•

•

•

The monitoring frequency is sufficient to identify any significant non-conformances that have occurred

The range of parameters being monitored is adequate (this is particularly relevant if an activity has led to an incident or complaint)

Changes to programmed construction activities are adequately covered by the monitoring programs.

Any proposed modifications to monitoring programs would be submitted to MMRA for approval prior to being implemented.

The contractors would hold responsibilities for the ongoing management of baseline and monitoring data to ensure the transparency and accountability of environmental management.

MMRA would be responsible for checking that baseline and other monitoring data meet the monitoring requirements of the MMRA EMS and ensuring that the stored electronic data sets are electronically readable.


Results of monitoring would be made available upon request to relevant interested parties to contribute to the improvement of environmental knowledge more widely.

23.8.2 Reporting Performance against each contractor's CEMP would be reported to the MMRA and relevant government agencies as appropriate. The CEMP would describe the reporting and external notification requirements in detail, including what needs to be reported and to whom and the timeframe for reporting.

Reporting and notification requirements would include, but not be limited to:

•

•

•

•

The contractor would be required to prepare monthly environmental performance reports to MMRA and the Independent Reviewer for the PPP contract. This report would include external and internal audit findings, monitoring results and incidents and non-compliances

Quarterly project activity report containing summary of key project activities

Notification to the Office of Aboriginal Affairs Victoria and DELWP if a potential Aboriginal site or artefact is identified

Notification to Heritage Victoria and DELWP if a heritage artefact is discovered.

23.8.3 Audits Internal audits would be undertaken (by both MMRA and the appointed contractors) to monitor environmental performance, and to ensure continued conformance with ISO14001.

External audits would be conducted to monitor environmental performance for each work package, and to ensure continued conformance with ISO14001. For the PPP contract, these external audits would be undertaken by the Independent Environmental Auditor appointed the PPP contractor. The other work packages would be required to undertake external auditing in accordance with their EMS.

MMRA's implementation of the MMRA EMS would be audited annually using an independent auditor.

Audits would be scheduled for all Melbourne Metro work packages (such as early works, Tunnels and stations, Rail systems and Rail infrastructure) to ensure project activities are in accordance with the MMRA EMS, Environmental Performance Requirements and the contractor CEMP. The audit scope would be prepared prior to each audit. In summary, audits would evaluate:

•

•

Conformance with EMS/EMP requirements

Compliance with Environmental Performance Requirements


•

•

Responses to non-conformances, incidents and complaints received

Effective implementation of monitoring programs.

The audit schedule would be determined on an annual basis for each work package and would take into account the following:

•

•

•

•

•

The timing of the proposed works

The nature of the proposed works including consideration of the level of associated risk

Incident investigation outcomes

Previous audit outcomes

Management review outcomes.

Conformance would be assessed through observation of project activities, interviews and review of records. Records would include the following:

•

•

•

•

•

Environmental monitoring, process monitoring and management performance monitoring results

Inspection and audit reports

Soil and waste management records

Surveys

Meeting minutes.

As a minimum, internal audits would be scheduled to coincide with the commencement of key activities and the use of key equipment, and on a quarterly basis (and more frequently where necessary) through the delivery of each work package. External audits would be scheduled on a quarterly basis (and more frequently where necessary) through the delivery of each work package.

The results of each audit would be presented in an audit report (the template to which will be agreed with MMRA at project commencement).

23.9 Contingency Measures The CEMP and OEMP would be required to include appropriate contingency measures to address identified environmental, social and business risks during construction and operational phases. Contingency measures may be required to take effect in the event that monitoring or auditing (or any other means) identifies:

•

•

•

Unforeseen issues; or

Issues which are foreseeable but not expected to occur; or

Impacts which are expected but which prove greater than anticipated.


Contingency measures would be developed to comply with relevant regulations, standards and industry best practice guidelines.

Examples of potential contingency measures include protocols for managing the discovery of previously unidentified historical archaeological sites and a plan to address the containment, treatment and disposal of any fuel and chemical spills. Contingency measures will also be a key part of the Cultural Heritage Management Plan for managing the discovery of previously unidentified Aboriginal Heritage sites.
